Title: Manufacture of piezo-electric ceramic filter
Inventor: EGUCHI TAKAYUKI
IPC: H01L41/39
Filed: 1979-01-08
Abstract: PURPOSE: To curb unrequired vibration and improve characteristics of filter by controlling the distribution of the grain size of ZrO 2  material and utilizing the same.  
     CONSTITUTION: On manufacturing a ceramic filter of system PbZrO 3 -PbTiO 3 - Pb(Mg 1/3 Nb 2/3 )O 3 , ZrO 2  containing >60wt% of its constituent with grain diameter of 1∼4μm particle size is used for one of the materials thereof. After being mixed up, these materials are calcined and crushed. Then they are press-molded and sintered. By using ceramics thus obtained, an element of piezo-electric ceramic filter is manufactured. If ZrO 2  containing 60wt% of its constituent with grain diameter larger than 4μm is used, the function as video IF filter for TV picture device is not atlained. On the other hand, the ceramic filter for which ZrO 2  containing 60wt% of its constituent with grain diameter less than 1μm is used has narrower band width of -6dB and small attenuation quantity of high-pass side.

Title: Rolled stock for pack rolling
Inventor: NAGAI ISAO
IPC: B21B1/38
Filed: 1989-01-07
Abstract: PURPOSE:To perform stable pack rolling by lapping a cover stock on both top and bottom surfaces of a core stock and putting a spacer stock between both cover stocks at both ends of the core stock and boring gas vent holes in upper and lower cover stocks at both end parts in the lateral direction of the core stock. CONSTITUTION:Gas vent holes 5 are bored in a cover stock 2 facing to both lateral ends of a core stock 1 contained in the cover stock 2 and a spacer stock 3. When the total stock is pack rolled, the core stock 1 and the cover stock 2 elongate along the rolling direction and lateral elongation of the stocks is hardly generated. By that, after rolling, the holes 5 are located in the core stock 2 facing to both ends of the stock 1 and are not crushed by rolling because the holes 5 are bored in the thickness direction. A hardly workable material, such as a titanium alloy or high alloy, etc., is used as the core stock 1 and an easily workable material, such as carbon steel, etc., is used as the cover stock 2.

Title: Taut belt-type measuring instrument
Inventor: FUJITA HISAYA
IPC: G01D11/06
Filed: 1983-01-10
Abstract: PURPOSE:To attain a measuring instrument which is thin and strong against oscillation, by increasing the deformation curvature of the part to which bending stress is applied repeatedly by the oscillation or the like of a tense belt and reducing that of other parts. CONSTITUTION:In an arc part 411 of an attaching member 410, a part A where bending stress is applied repeatedly to a taut belt 210 by the oscillation or the like of the taut belt 210 has a larger deformation curvature. Parts B and C where bending stress is not applied to the taut belt 210 have a smaller deformation curvature. The attaching member 410 is thin because of this shape. Thus, even if the whole of the measuring instrument is made thin, the accident of the break of the tense belt due to the oscillation or the like is prevented.

Title: Address decoder circuit
Inventor: MINORIKAWA KAZUO
IPC: G06F12/00
Filed: 1979-01-17
Abstract: PURPOSE:To simplify the circuit constitution by giving the control to the address decoder output which designates the addresses before and after the address of the n-th address signal via the logic gate. CONSTITUTION:The output of AND gates G0-G6, G8-GA and GC all become 1 in case address signals 2<3>-2<0> which designate register R0 are all zero for example. And at the same time, the signals which designate registers R7, RB, RD and RE all become 1. As a result, registers R1-RE are designated in duplication with the address signal which designates register R0, and the data to be written into R0 is also written into R1-RE. Then the writing to the register to receive the writing originally is duplicated to the registers to receive the subsequent writing thus to be written with the same data. And no designated is given to the preceding registers, and thus the prescribed data is written into each register.

Abstract: PURPOSE:To recover zinc together with iron and lead with high purity with just one kind of acid and at a short stage by leaching blast furnace dust with an aq. nitric acid soln., and separating lead by sulfiding and further iron by extraction from the liquid obtd. by dissolving and separating iron, zinc and lead in the dust. CONSTITUTION:When dust contg. iron, lead and zinc is leached in an aq. nitric acid soln. in a tank, the above-mentioned metals are dissolved as Fe<3+>, Pb<2+> and Zn<2+>. The iron-rich insoluble residue contg. virtually no lead and zinc is produced at this stage and therefore the residue is separated away and is reused for an iron source. A material which produces S<2+> in the liquid and maintains the acidity of the liquid, for example, gaseous H2S is blown into the liquid in the tank contg. the above-described respective ions, Pb<2+> settles as PbS. The PbS is separated away and is reused as a lead source and thereafter an aq. soln. contg. Zn<2+>, Fe<3+> is solvent extracted with an acidic extracting agent having affinity to Fe<3+> whereby the soln. is separated to an iron extract and an aq. soln. contg. 2n<2+>. The former is reused as an iron source and the latter is separated an recovered as Zn(OH)2 after neutralization with an alkali.
